I changed my MTU settings and now I'm getting "cannot connect to the server within the time limit" when attempting to sign into PSN, which is a slightly different error than what I've been getting since the problem started.
Man, I can't believe it's been five days.
I was having similar issues. First I turn off the connection on the internet on the PS4 and then reboot it. After the reboot I disconnected the wifi if it automatically set on then I connected manually to the wifi and then changed the MTU to 1473. The initial connection to PSN during the test will tell you that it failed, but if you try to log in manually to PSN either on the PSN settings or trying to access the store or your trophies you should get online.
I say this because after Xmas I couldn't get online even after changing the MTU but after disconnecting and reconnecting manually my WIFI everything worked since and I haven't been disconnected from PSN since.
